most likely idle air control valve on throttle body remove rubber air duct that runs from air filter spray real good with carb spray wait 30 minutes for it to dry should improve condition

- Wiper relay stuck closed.

Your windshield wiper motor is probably bad.

get proper size normally passenger side and drivers side different lengths ,woul replace them with proper size or you might damager wiper motor

remove the wipers from the arm by removing the nuts,then the plastic grill brlow wipers and the you will see the motor.

I think you should change the wiper motor I had the same problem with my toyota echo good luck

Did they check your wiper switch, more then likely bad switch.That where it get it's power from.

Open the wiper panel located at below wiper arms,
it could be any of wiper mechanism untight
